For (small) business with not enough transactions, accepting debit cards is an expense
Here in Ireland it's not uncommon for shops to insist on cash only for amounts less than €10 (except in some extrenuation circumstances (like the ATM in their shop being broken)).
Credit card acceptance is very very low.
That has definitly not been my experience. Perhaps you are thinking of chip-and-pin credit cards. Here in Ireland (& IME UK), credit cards are accepted in many, many point of sales/retailers. But they might only accept chip and pin credit cards, which I believe are uncommon the USA.
In the Netherlands very few stores accept credit cards, most accept just the dutch "PIN" and "Maestro" (=EMV). Not many people in the Netherlands have a credit card.
Vice-versa however, I was able to pay at WalMarts in the US with my Dutch debit card with no issues (once I hit the right button, it's confusing).
